Set the Expiration Date on Your Google Drive, Docs, Sheets

This is a useful tool for students and teachers who create presentations and documents that will incorporate materials that will need to be updated, but they might not necessarily go back and do so.   If you create a document and don't plan on ever editing it again, think about the content. Will any of it still be relevant a year from now, does it contain research that will not be current in 2 years?  Set an expiration date.
